Our production process in storage compartment experienced three stages:
        First stage: the whole structure injected foam metal skin.
        The first generation of refrigerator manufacturers are using this technology. This product has a box because body metal material existence, forming a cold Bridges, On the other hand, the thermal insulation layer of injected foam is found within the inner quality defects and to guarantee, Moreover, because neither do insulation foam material and adhesive bonding, easy generation is unsound, heat preservation effect is not ideal, leakage rate of heat conduction coefficient (high).

        The second stage, the whole structure injected foam glass.
        In the second and third generations after the refrigerator is using manufacturing enterprises. This product in the first stage of the product and improve the step, light weight, low leakage rate of heat conduction coefficient), reduce (heat preservation effect is good, but there are bonded carriage, the skin is goo bleb defects.

        The third stage, polyurethane fiber bonding plate structure.
        In the second and third generations after the refrigerator is using manufacturing enterprises. This product is light weight, heat leakage rate, low thermal conductivity (heat), good effect. Use of unsaturated polyester resin as binder, plus a cushion, with the rigid polyurethane foam insulation materials, high strength, low thermal conductivity. Plate with high strength and high bond cement, forming a whole sealing. The only flaw is bigger loss after cutting polyurethane materials with high cost, thus. Especially in the current chemical raw materials price severe cases, the production cost is getting higher and higher.

        The structure of the refrigerator in the domestic and international market dominant, China is currently representative refrigerator manufacturers use process.
